1 0 (2H whom it may concern:

Be it known that I, Ciiannns A. Mtin'sox,

:a citizen of the United States, residing at and cer-

lVillian'ison, in the count of liflingo State of West Virginia, have iniented tain new and useful improvements-in his tallic Packing, of which the. following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in metallic packing, and an object. thereof is the provision of a packing which is eapable of adjustment to con'ipensate for the wear of the parts.

A further object ofthis invention the provision of a packing comprising a series of rings which are adapted to encircle the piston rod of a locomotive, the rings being formed in sen'iieircular sections. and the diameter of the inner periphery of the rings being relatively of less degree than the diameter of the piston rod, whereby the rings are capable of adJustment to compensate for the wear of the parts.

A further object of the invention is the provision of a packing which consists ot' a series of rings which are adapted to encircle the piston rod, the several rings being teleseoped upon one another whereby tight joints between the several rings are provided.

With these and other objects in view, my

invention resides in the novel features of construction and arrangement of parts to be hereinafter more fully descriloed, claimed and illustrated in the accompanying drawings in which,

Figure 1 is a side elevation of the packing mounted on the piston rod. Fig. 2 is a longitudinal section thereot, and Fig. 3 is a section taken on the line 3-3- of Fig, 2

Referring more particularly to the drawing, the numeral 1 designates the piston rod of a locomotive or other machine, and the numerals 2, 3 and 4: indicate a series of inclosing rings. Each of the rings is formed of two semicircular sections 5 and the outer r periphery of each of the rims is formed with a groove 6 for the reception of aunu lar spring members 7 whereby the sections are held in frictional engagement with the piston rod. The outer ring 2 is formed on its inner periphery with a laterally extendmg rib 8 which is adapted to engage with an annular recess 9 in the ring 3.

The

sections of the rings are spaced ring 3 is also termed with li erally pro jecting annular rih it: which is adapted to rest within the annular grimvc l1 formed in the inner rin i oi the packing. it wilt he seen that one this construc ion, the rings telescope upon one another wherehv tight joints hetwecn the rtepeetive rings a: provided.

The inner ring; of the packing is preferably relatively longer than the 5 rings of the device. and the ring; is beveled on one end as at i1] wh" the ring may he frictionallv aged with the valve box (not shown) oi? the piston rod,

T he o 'ieration oi? my device is as followsz-in the practical u thereof, the rings are placed on the end oi? piston rod. and moved upwart on the rod il 1 inner ring rictionaily engage: box of the piston rod. it will he sy when therin are placed upon the pist-i bx) rod, the opposing faces ot' the son-l apart and the annular spring member 7 in the groove (3 in the rings, i i-"ill only hold saidringgs in close contact with the piston rod. it will he seen that any weu'r on the inner periphery of the rings, will he compensated for by reason of the pressure at the spring Writ" hers '7 upon the sections of the ring.

While have illustrated three rings as constituting my packing, it stood that any desired number at he used and that I do not. limit this regard,

The rings are preterahly constructed of metal of a soft composition, so that the rings may readily conform to any lateral disalinement ot' the piston rod. it will he seen from the drawing that the spaced opposing edi of the several sections are out of aiiuell'ltftltwith each other so as to prevent an opening through the packing through which steam end water from the valve casing might escape.

From the above description taken in con accompanyi drawing. it

ri ngs may myself in nection with the will be seen that l have pro ided a packing which is simple in COHSUUCUOD, which ma he cheaply manufactured and which will fulfil all the requirements of such a. device.

Having thus dcscrihcd my invention, what it desire to claim and secure by Letters Patent is r-- v The combination with piston rod, out a will he underplurality of rings, each of said rings being formed of a plurality of seg'mentnl'seotions constltuting 1n comblnatlon a general c0neshaped packing, spring band engaging the said sections for normally forcing said sections inwardly toward each other, the adjacent sides of the rings being disposed in a plane perpendicular to the axisthereof, annular ribs formed upon the rings, the peripheries of said ribs being disposed in planes pnrallel with the axis of the piston 1 rod and the ends of the ribs being disposed in planes perpendicular to the nxis of the piston rod, and corresponding sockets formed in certain of the rings for receiving 1 said ribs.

In testimony whereof I hereunto affix my signature in the resence of two witnesses. CI-IARL S ALBERT MUNSON. Witnesses v CLYDE SPAULDING, CHARLIE PEAK.
